Chemical Information

Cyclo(his-pro)

Cyclo(L-His-L-Pro) is a homodetic cyclic peptide resulting from the formal condensation of both the amino and acid groups of L-histidine with the acid and amino groups of L-proline. It is a metabolite of thyrotropin-releasing hormone (TRH). It has a role as a dopamine uptake inhibitor, an anti-inflammatory agent and a human blood serum metabolite. It is a homodetic cyclic peptide, a member of imidazoles, a dipeptide and a pyrrolopyrazine. It is functionally related to a L-histidine and a L-proline.
